In case this is useful to someone, here is a quick function i built out to replace blank strings with N/A's in lists of lists (python 2).

y = [["1","2",""],["1","4",""]]

def replace_blank_strings_in_lists_of_lists(list_of_lists):
    new_list = []
    for one_list in list_of_lists:
        new_one_list = []
        for element in one_list:
            if element:
                new_one_list.append(element)
            else:
                new_one_list.append("N/A")
        new_list.append(new_one_list)
    return new_list


x= replace_blank_strings_in_lists_of_lists(y)
print x

This is useful for posting lists of lists to a mysql database that does not accept blanks for certain fields (fields marked as NN in schema. in my case, this was due to a composite primary key).
